Optima Memory is the perfect upgrade to boost the performance of your PC, for casual gaming or your Vista experience. PNY memory upgrades improve the overall system performance for an outstanding value with speeds and densities compatible with all popular desktop and notebook PCs.

DDR2 is the next generation of DDR memory. DDR2 memory features faster speeds, greater bandwidth, lower power consumption and enhanced thermal performance.
